Modern-day kindergarten teacher Yan Yu drowned while saving someone. When she opened her eyes again, she had become a maid in the Prince of Jing's residence who had just "died once."
Everyone in the residence feared her, despised her, and wanted her dead.
Only the young heir clung to her leg and called out in a childish voice:
"Mother!"
The regent stared at her face, identical to that of his late consort, his gaze dark and unreadable.
"Who are you, really?"
Though she was an outsider who had arrived from the modern world, she seemed born to belong in this deep palace.
The wife he had longed for had appeared in the form of a maid, throwing his world into chaos.
Murderous schemes stirred beneath the surface of the residence, and it was impossible to tell truth from falsehood.
Memories from three lifetimes lay hidden, with danger at every turn.
She was the moonlight in his heart, and the fate he could never escape across three lifetimes.
She was no substitute. She had crossed three lifetimes and truly returned.
